I haven't seen it in action, but I suspect anything Rick drives starts when he wants it to. He's probably owned more CUCVs than anybody in the country except the federal government. He's solidly in the #2 group
I listed above. You will not go wrong by listening to his advice.
I've got the Doghead mod and the resistor bypass. I'm not expert enough to know when a single GP is going out, so I like the resistor bypass. I don't trust the stock starter relay, so I have the Doghead mod. Works for me.
If I ever have another CUCV, it will get a standard automotive relay in a proper socket instead of the Doghead 100 amp job, but it
will get changed from the stock GM relay. in fact, if I ever need to replace my GP relay, I'll probably steal my starter relay and put a standard relay in its place.
There ya go. Pick yer poison.
